Improvement in the manufacture of skirt-wire



' UNITED STATES PATEIL/QELISL T. S. SPERRY, OF NEW YORK, N. Y.

IMPROVEMENT IN THE MANUFACTUPLE OF SKIRT-WIRE.

Specification forming part of Letters Patent No. 46,718. dated March 7, 1865.

To all whom it may concern:

Be it known that I, T. S. SPERRY, ofthe city, county, and State of New York, have invented a new and 'useful Improvement in the Manufacture of Skirt-Wire; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable Others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in Which- Figure 1 represents a side elevation ot' my invention. Fig. 2 is a longitudinal section of the same.

Similar Y letters of reference indicate like p rts.

Skirt-wire as now manufactured is covered with cotton or other fibrous material laid on by skirt-wire, said wire to be applied by braiding or simply by windingr it on in such a manner thata permanent and durable covering for the skirt-Wire is obtained, which will ei'ectually protect said wire and not be liable to peel on" or wear out.

A represents a piece of skirt-wire made in the usual manner, either single or double, as

may be desirable. This wire is covered by metal wire B, which may be wound 0n, as shownin thedrawings,or which may bebraided on in the same manner as cotton thread, or which may be applied in any other suitable manner. For this purpose ot' covering skirtwire I use, by preference, iron or brass wire, which is tinned or coated with zinc, or otherwise rendered non-corrosive, and by using such wire a covering can be produced which Will give to the skirt-wire a very handsome appearance, and which also will be durable and not be liable; to come ott'; but if the use of such non-corrosive wire should be too expensiveior general use, ordinary plain iron or brass wire may be used, and it the same is thin enough and properly annealed it can be laid on by braiding precisely like cotton thread or other fibrous material, and considering the present high price of cotton the metal-covered skirtwire will be able to compete advantageously with the skirt-wire covered in the ordinary manner.

I do not claim covering a central core of metal with a wrapping or coil of wire, as that has been before practiced 5 but What I claim as new, and desire to secure by Letters Patent, is-

The above-dcscribed skirt-wire, as an article of manufacture, consisting of a close-coiled covering of wire, vwith a non-corrosive surface, over a central skirt wire, substantially as described and represented.

T. S. SPERRY.
